Court documents are revealing more details of the alleged threat at Millwood High School on Tuesday.
The documents allege the 18-year-old charged in the incident made threats toward Catharine Burton. The school’s website lists a Cathy Burton as the school’s vice-principal for grades 11 and 12.
Jonathan Murray, 18, has been charged with threatening to cause Catharine Burton bodily harm or death.
The nature of the threat or how it was received remains unknown. Murray was arrested in connection with the lockdown at Millwood High School on Tuesday.
“Those are incidents that we don't like to hear about, but I am reassured that school boards and individual schools are well prepared,” said Nova Scotia Education Minister Karen Casey.
Police declined to confirm whether the threat was made against the school's vice-principal, as did the school board, saying the matter is before the courts.
Two teenage boys were remanded Wednesday on 20 weapons-related charges each in connection with the discovery of a bag of weapons and ammunition in woods near the high school.
The teens are not charged with uttering threats.
Court documents also confirm police believe those boys took the guns on a city bus.
Halifax Transit confirms two people matching the descriptions of the accused were seen on board one of its buses, and disembarking on Millwood Drive.
A transit spokesperson also says although buses are equipped with cameras, there's really nothing to prevent a person from boarding a bus with guns.
“Certainly it is a public transit service,” said Tiffany Chase of the Halifax Regional Municipality. “We don't have metal detectors in place at our terminals or on board our buses, but the cameras are a bit of a preventative measure in terms of the fact that someone knows that if they do commit a crime … they will be caught on camera.”
The 15- and 17-year-olds charged with weapons offences remain in custody.
They're due back in court on Friday for a bail hearing.
